Single spring, rubber diaphragm seal, similar to Type 11/22, but with reduced O.D. (D3) to give full ANSI seal chamber compatibility.
Type N11 with a resilient elastomer mounted face is the preferred design supplied up to its design limit of 2.000” / 50 mm.
Type U11 features a retainer lug driven face and is the preferred design for all sizes above 50mm/2.000".
Also available as assembly Type N11J or U11J with a Type 31 centrally ‘O’-Ring mounted seat to fit same housing sizes and working lengths.
